Even with all the advances in technologies, humans continue to suffer from the consequences of flooding century after century. This book covers two pertinent topics: flood risk and flood management. Experts world-wide share their knowledge on these topics and highlight solutions to the flooding problems in the 21st century. Topics discussed in this book include spatial explicit multi-criteria flood risk; identification of social obstacles in solving flooding problems in Buenos Aires Province, Argentina; participative planning processes in flood risk management and in integrated watershed management; new economic instrument for integrated management of muddy flow risks; flood hazard mapping using hydrodynamic modelling approach; and simulation of flood reduction by means of complex structural measures using hydrodynamic modelling and aerial photogrammetry-derived digital surface model (DSM).
